About this study
Official title: Anti-hypertensive Effect of Fermented Mycelia of Antrodia Cinnamomea Among Mild Hypertensive Subjects in a Double-blinded Randomized Trial
This the first report undertaken to assess the effect of supplementation with oral gamma-aminobutyric acid (GABA), adenosine and antrosterol-containing AC mycelia on blood pressure among people with mild hypertension. Overall, AC mycelia consumption for 8 weeks could successfully reduce mean diastolic and systolic BP through the suppression of PRA that is linked to downstream suppresion of angiotensin II formation, which further decreases the sympathetic outflow that leads to hypertension. In addition to blood pressure lowering properties, AC mycelia also has beneficial effect in reducing oxidative stress, significantly. No adverse events were noted, suggesting that AC mycelia deserve its consideration as a candidate for safe alternative treatment to conventional anti-hypertensive medications.
Read the detailed description
This the first report undertaken to assess the effect of supplementation with oral gamma-aminobutyric acid (GABA), adenosine and antrosterol-containing AC mycelia on blood pressure among people with mild hypertension. Forty-one subjects with systolic blood pressure (SBP) between 130 and 179 mm Hg and/or diastolic blood pressure (DBP) between 85 and 109 mm Hg were randomized to receive either AC mycelia or starch placebo for 8 weeks, and had follow-up observation for an additional 2 weeks. SBP in the subjects given GABA, adenosine and antrosterol-rich AC mycelia significantly decreased compared to those who received the placebo (p<0.05). DBP also decreased after the intake of AC mycelia. Compared to the placebo, AC mycelia significantly reduced plasma renin activity by a maximum of 25 % and 36 % on week 8. This suppression suggested that AC mycelia is a potent inhibitor of renin, and its bioavailability is sufficient to produce BP reduction after a short term of oral administration. Neither adverse events nor abnormal laboratory findings were noted throughout the study period, suggesting that GABA, adenosine and antrosterol-rich AC mycelia significantly decreased borderline hypertension, which may support its consideration as a safe alternative treatment compared to conventional anti-hypertensive medications.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AC myceliaDietary supplement
Also called niu-chang-chih
An 8 week double-blinded randomized placebo-controlled parallel study with 2 week follow-up period was performed in mild hypertension subjects. Consenting eligible subjects were receive three capsules per day containing either 420 mg of AC mycelia of similar appearance for 8 weeks. The subjects were required to visit at baseline, every two weeks during the intervention period (8 weeks), and at follow-up 2 weeks after treatment had ended. During each study visit, systolic and diastolic BPs were recorded, fasting blood samples were collected and anthropometric measurements were performed. Compliance was evaluated using a food diary and monitored with biweekly telephone calls.

The record says: finished, as of the sponsor's last update on 26 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
AC anti-hypertensive measure blood pressure (SBP and DBP ) (time frame: 10 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02532699, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Aug 2015.
